Perhaps you should try some spelling variations:
"allocation optimization algorithmsssssss" » "allocation optimization algorithms", "allocation optimization algorithmssssssss", "allocation optimisation algorithmsssssss", "allocation estimation algorithmsssssss", "location optimization algorithmsssssss"
"parameter optimization algorithm" » "parameter optimization algorithms", "parameter optimisation algorithm", "parameter estimation algorithm", "parameters optimization algorithm"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("allocation optimization algorithmsssssss") OR ("parameter optimization algorithm"))~.
• Removing quotes may allow a broader search: (( allocation optimization algorithmsssssss ) or ( parameter optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("allocation optimization algorithmsssssss") or ("parameter optimization algorithm"))*.
